Criminal justice client rehabs can be considered being a considerably better option than incarceration or significant fines for individuals who have already been convicted of any sort of alcohol or drug related crime. For example, someone who has been found guilty of driving under the influence of alcohol or drugs may be eligible to obtain rehab services for problem rather than serving time in jail. The judge might order that the individual receive rehabilitation, either alone or together with other consequences. First time offenders specifically are often given the opportunity select a criminal justice client rehab rather than other sentencing, and it is well-advised they reap the benefits of it when it is a possibility. The concept behind criminal justice client rehabs is that it is much more effective and efficient to invest time and energy into treatment than enforcement of other consequences. Much research has been done to find out how effective this approach is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. All indicators appear to be quite positive, and criminal justice clients who do experience rehab have better chance of remaining out of the system after rehabilitation.
